Short/wide board like I-131 will respond better to active sailing style (pumping, riding the fin),
if you don't like it, pick something longer, narrower like Futura or Lorch , I-121 as some other post recommended.
Looks like if I don't want to pump too much, I will be better off with longer and narrower boards. Is iSonic 121 enough for planing with 8.5 in 10mph-12mph too? Does wood carbon boards make a lot of diffence in early planing compared to all wood boards? Your comments are appreciated very much!
